    We get quite a handful of enquiries for D38999 series III square flange receptacles these days, and part number D38999/20FD15PA keeps popping up from project engineers.

    This is a 20‑style square flange receptacle with F‑code electroless nickel shell finish, D shell size, 15‑position insert layout, crimp male pin contacts. It fully follows MIL‑DTL‑38999 series III requirements. Anti‑tilt scoop‑proof design prevents contact damage during careless mating. Solid 360‑degree EMI/RFI shielding cuts down outside signal noise. Operating range runs from ‑65℃ up to +200℃, IP‑grade sealing works for humid, salt‑fog exposed spots.
    A lot of our customers deploy this unit inside avionics boxes, ground defence hardware and heavy industrial automation cabinets. Crimp‑style contacts make field assembly fairly convenient. Keep in mind, fluorosilicone seals can be added if your hardware sits around oil or fuel vapour — we often adjust this upon client request.
    At our facility in Luoyang, we run full final‑unit inspection after assembly. We can handle small prototype batches as well as volume production runs. Custom plating or modified tail accessories are doable, though non‑standard changes will push out lead‑time a little bit.

    If you are evaluating this part for your hardware build, feel free to reach us for datasheets or physical samples for lab validation.


    Mass production

    Every D38999/20FD15PA square flange receptacle we supply goes through our complete in‑house production workflow, no outsourced finished assembly work.
    We kick things off with mould development. Insulators and sealing bodies are produced by custom mould tools. Shell parts including socket shell and plug shell get shaped on our CNC workshop. All raw components are checked before moving to assembly station.
    Workers put together insulators, sealing bodies and precision‑machined metal housings to build up complete connector units. This D38999/20FD15PA is Series III 20‑size square flange receptacle with 15‑position male crimp contacts, electroless nickel shell finish. Anti‑scoop‑proof insert, solid EMI shielding and wide‑range temperature resistance are built‑in features right from component stage.
    Once assembly work wraps up, every single piece heads for the inspection zone. Operators run visual microscope check, dimension verification and performance tests as our OQC standard. We reject parts with tiny plating scratches, insert shift or contact deformation before packing.
    Qualified goods go into anti‑static packaging. We handle both small prototype lots and large volume orders. When shipment is ready, we work with mainstream international couriers to deliver parcels worldwide.

    With more than 13‑year connector‑making background, we can adjust sealing material or shell surface finish according to your real‑world working environment. Reach out if you need datasheets or sample units of D38999/20FD15PA for your project evaluation.


    How to purchase


    流程图.jpg

    From daily inbox, D38999/20FD15PA is one of the frequently asked square flange receptacles under MIL‑DTL‑38999 Series III.
    Some engineers just need standard off‑stock units. Others come with small tweaks, because their on‑site working environment cannot fully fit the original spec. That is exactly why we set up this complete one‑stop ordering flow.
    Simply drop our customer service line first. Tell us your real application scenario. If you require any changes, send over your custom drawings or notes. Our technical team will go through your request, check feasibility and work out a practical solution, instead of giving you blind promises.
    After all details are aligned, we send out formal quotation. For project‑based purchases, most buyers will not jump straight into mass production. They hope to get physical D38999/20FD15PA samples and run lab tests first. We totally understand this concern.
    Once sample performance gets approved and payment is settled, we kick‑off production. All parts are manufactured in‑house, covering mould work, CNC shell machining, assembly and full OQC inspection. Any custom adjustment will bring extra lead‑time, and we always point this out clearly at quoting phase.
    When finished goods pass inspection, we pack them properly and arrange international delivery.

    No matter you need a handful of samples or large batch supply, feel free to write us for D38999/20FD15PA related support.

    Exhibition


    未标题-3.jpg


    Trade exhibitions remain one of our favourite spots to meet real‑world overseas partners in person.
    At our booth, lots of international visitors stop by to check out our high‑performance circular connector lines. Some guests come with clear project targets already in mind. They bring over their actual application challenges and sit down with our team for direct technical exchanges.
    You can see from our show photos: our sales and technical staff spend quite a lot of time talking through sample parts, drawing details and modification possibilities face‑to‑face. Many buyers want to touch and examine the MIL‑DTL‑38999 series units on display, rather than only reviewing pictures online.
    Quite a number of enquiries started right at these exhibition conversations. Clients share their hardware working conditions, ask about lead‑time, test reports and custom options. It’s much easier to clear up doubts when we can look at physical samples together.
    Even after the show wraps up, we keep following up with these contacts. Some move on to request lab samples, others proceed to formal bulk order evaluation.
    For us, joining industry shows is not only about product display. More importantly, it builds real trust. If our schedule allows, we hope we get the chance to meet you at one upcoming industry event.
